An acronym used by 12 year olds who think they are unbeatable internet trolls. They often consider themselves as internet gods who shall never be defeated as long as they have sweg. Sometimes, they enter the deep web, order some sweg then inject it into their bodies. In other words, they are fucking badasses.

" Damn dude i just got tr0ll3d H4rd "
" i told you to watch out for the internet gods "

sweg is what some people started using after others started saying swag was an acronym for secretly we are gay. but since then others have started saying sweg is an acronym for secretly we EAT gays which is not much better.
